Fatal error code 406 using hbc when filtering by location

Question

I'm trying to use the Twitter hbc library to get tweets based on locations. I've set up my code according to the example file FilterStreamExample. The example works, but when I try to add a location to the endpoint, I get Fatal error code: 406.

Here's the code that works:

StatusesFilterEndpoint endpoint = new StatusesFilterEndpoint();
endpoint.trackTerms(Lists.newArrayList("twitterapi", "#yolo"));

But when I add the following code, I get the error:

Coordinate southwest = new Coordinate(-87.648926, 41.883109);
Coordinate northeast = new Coordinate(-87.606354, 41.828050);
Location chicago = new Location(southwest, northeast); 
endpoint.locations(Lists.newArrayList(chicago));

Thanks for the help!

EDIT Here's the entirety of my code:

public class App {

  public static void oauth(String consumerKey, String consumerSecret, String token, String secret) throws InterruptedException {
    BlockingQueue<String> queue = new LinkedBlockingQueue<String>(100000);

    StatusesFilterEndpoint endpoint = new StatusesFilterEndpoint();
    Coordinate southwest = new Coordinate(-87.857666, 41.657347);
    Coordinate northeast = new Coordinate(-87.587128, 41.795712);
    Location chicago = new Location(southwest, northeast); 
    endpoint.locations(Lists.newArrayList(chicago));

    Authentication auth = new OAuth1(consumerKey, consumerSecret, token, secret);

    BasicClient client = new ClientBuilder()
      .name("exampleStream")
      .hosts(Constants.STREAM_HOST)
      .endpoint(endpoint)
      .authentication(auth)
      .processor(new StringDelimitedProcessor(queue))
      .build();

    // Establish a connection
    client.connect();
    PrintWriter writer;
    try {
      writer = new PrintWriter("twitterstream.txt", "UTF-8"); 
// Do whatever needs to be done with messages
      for (int msgRead = 0; msgRead < 1000; msgRead++) {
        if (client.isDone()) {
          System.out.println("Client connection closed unexpectedly: " + client.getExitEvent().getMessage());
          break;
      }
      String msg = queue.poll(5, TimeUnit.SECONDS);
      if (msg == null) {
        System.out.println("Did not receive a message in 5 seconds");
      } else {
        writer.println(msg);
      }
    }
     writer.close();
        } catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
      e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
      e.printStackTrace();
        }  

        client.stop();
}

  public static void main(String[] args) {
  try {
      App.oauth("LEDrJPDhn6C2trbde95WZg", "gEmlgewUodOoDjMNl2QbcqsbGvYDxNZWNRULchPE", "292576546-SWzEgMU7mC7Haat3lLEOQ0mXsZFwBf8F3ZKLBMVa", "ajPN2rGLx57yPoUjYe2qN4bE763orux4KwYeoCAvuLRPM");
  } catch (InterruptedException e) {
      System.out.println(e);
  }

}

Answer 1

I have checked your code with yours and mine Outh parameters. With mine it works and it doesnt work with yours. This is the problem

Answer 2

Maybe the problem be the coordinates. You should verify on http://boundingbox.klokantech.com/. Choose the option "csv" after that to delimit the place.

Answer 3

Are you using Google Map coordinate ? Because It seems that you should switch your coordinate point.

Coordinate southwest = new Coordinate(41.657347, -87.857666);
Coordinate northeast = new Coordinate(41.795712, -87.587128);
